The State of Sennianus is a gargantuan, efficient nation, ruled by Senna with an iron fist, and notable for its daily referendums, multi-spousal wedding ceremonies, and irreverence towards religion. The compassionate, cynical, cheerful population of 32.272 billion Sennianians are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The tiny government juggles the competing demands of Education, Administration, and Healthcare. It meets to discuss matters of state in the capital city of Sennapolis. The average income tax rate is 3.0%, but much higher for the wealthy.

The frighteningly efficient Sennianian economy, worth an astonishing 12,169 trillion sents a year, is quite specialized and led by the Tourism industry, with major contributions from Information Technology and Book Publishing. State-owned companies are common. Average income is an amazing 377,106 sents, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The nation is ravaged by daily union strikes, banning party poppers has been a real party pooper, community organizers have given up going door to door because nobody is home, and artificial intelligences seeking exciting work are overcome with ennui. Crime, especially youth-related, is totally unknown. Sennianus's national animal is the dwarf goat, which is also the nation's favorite main course, and its national religion is Sennism.

Sennianus is ranked 320^th in the world and 1^st in belgium for Most Scientifically Advanced, scoring 1,337.14 on the Kurzweil Singularity Index.
